VALVE FOR INTERMINGLING AND CONTROLLING FLUIDS.

To all whom it may concern:

Be it known that I, ARTHUR WV. WEEDEN, citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Valves for Intel-mingling and Controlling Fluids, of

- which the following is a specification.

supply.

The nature and characteristic features of the invention will appear by reference to the accompanying description and drawings in illustration thereof which describes and shows my invention as embodied in a bath valve or faucet and the novel features of the invention will be hereinafter defined in the claims. Y

In the drawings,-Figure 1 represents an external view in side elevation of my invention, as embodied in a bath faucet. Fig. 2 is a plan view of the top of my valve or faucet illustrating more particularly the form and construction of the controlling lever or handle. Fig. 3'is a side elevation of my invention principally in section illustrating the interior arrangement thereof. Fig. 4 is an elevation showing the rotatable plug used in my invention detached from the valve orfaucet. Figs. 5 and 6 are respectively sections taken on planes 0cm and g y in Fig. 3. Fig. 7

is a section taken in the plane 2'z, in Fig.

1. Fig. 8 is a plan view showing the packing washer used in connection with my improved valve. Figs. 9 t o-17 inclusive are a series of views representing the development of the interior surface of the valve body and the exterior surface of the valve plug, and showing the successive relations of the openings formed in the valve plug to the ports formed in the valve body as the valve plug is rotated for the purpose of .controlling the flow of fiuidthrough said valve. Figs. 18, 19 and 20 represent. similar developed views showing the different relations of the plug openings and the valve inlet ports which are effected by a longitudinal Specification of Letters Patent.

Application filed November 21, 1910. Serial No. 593,468.

Referring to said figures, 1 represents the 7 body of my valve, comprising preferably a substantially cylindrical hollow shell having openings or inlet ports, 2 and 3, provided on one side and adapted, preferably by pipe threading, to receive thepipes 4 and 5, forexample, adapted respectively to supply hot water and cold water. The lower end of said valve body forming the discharge outlet is preferably threaded and forms a part of a'union for attaching the discharge pipe 6. The upper end of said body is preferably threaded to receive a cap 7 by which the plug and other parts hereinafter referred to are secured within the valve body.

lVithin the valye body, as shown in Fig. 3 is located the rotatable and preferably iongitudinally movable plug 8, said plug being adapted to fit within said valve body in substantially leakage proof relation. The upper end of said plug is provided with a preferably flattened tongue 9 which extends through a central opening formed in a bushing 10 rotatably. mounted in cap 7. A handle 11 is pivotally secured to the external end of said tongue 9, as will be hereinafter more particularly described, by which the valve may be rotated with respect to the faucet body or may be longitudinally shifted therein.

The rotatable plug 8 is hollow and, as more clearly shown in Figs. 3 and 4 is formed with laterally elongated plug openings 12 and 13 which are cut in'and extend circumferentially partially around the plug. Said openings 12 and 13 respectively cooperate with the inlet .ports 2 and 3, formed in the valve body and through which the supply pipes 4 and 5 are respectively adapted to discharge, in controlling and regulating the flow of liquid through the valve in a manner to be hereinafter more fully set forth. Said inlet ports 2 and 3 are preferably. of rectangular form, and are of an area which permits an unobstructed flow to the.

full capacity of the supply pipes therenormally the width of the plug openings exactly registers with the height of'the inlet ports,.and coincides therewith when super-' I imposedv thereon.

'respect to each other. that one portion of each, for example, the'right hand end of the opening 12 and the left hand end of the opening 13, as shown-in Fig. 4, simultaneously register in maximum relation with their respective cobperating inlet ports so as to permit the maximum flow simultaneously through each in one of the positions of rotation of the plug in the valve body. From such simultaneously registering portions the plug openings are laterally elongated or extended in mutually opposite directions One of said plug.openings for example, 12, ex-

tends circumferentially around the surface of the plug 4*for a distance at least exceeding twice the circumferential length of its 1 cooperating inlet port, toward the left as viewed in Fig. '4. The other plug opening 7 13- is elongated in a similar manner so as to extend circumferentially-around the valve 'in the opposite direction, or toward theright, asylewed in Fig. 4. Packing rings may be'providedif desired, as at 14 and 15,

the former being secured around the neck,

9 of the plug 8 by means of a-washer' 16.

' The operation of my invention in controlling the flow of liquid to my valve is more clearly understood by. the 31d of the developed views shownin Figs., 9 to 20 inclusive. In said views like characters or figures are applied to like parts throughout. In said vlews the observer is assumed to be looking through the inlet ports formed in the valve body toward the plug, brepresenting that portion of the internal surface of the valve od in which the ports 2 and 3 are located,

' wh-i e ;0 represents the developed surface of the plug having the plug openings 12 and 13 formed therein,sa1d openings 12' and 13 beingsh'ownby'idotted lines except as such ogenlngs register withthe inlet 't The ectiveareas through which the fluid sup.-

ply is permitted to 1 flowL-are indicated by shading. '-Referring to said Figs. '9. to 17 inclusive, the surface pot the plug 8 is assumed .to be in the process of rotation within the valve bodyb by means-ofthe' controlling.

lever 11, and itsisurface p to have reached,

in Fig. 9, a position: with respect to the body surface .6 wherein thefleft vend of lug openi'n'gj12 is approaching the edge '0 the inlet port 2. "In such position neither valve.

opening 12 nor 13 in any place registers with either. of the inlet pgrts 2 or 3, and consequently therewill no flow whatever of liquid through the valve. Upon further rotation of the plug until theplug surface ;0 and the body surface I) come into the relation shown in Fig. 10, the left hand end of plug opening 12 will come in registration with the port 2 for a portion 'of the width of. the latter, and that portion of the area of the opening 12 and of the inlet port 2 which are in registration, such area being shown as shaded 1n the figure, will be effective to'permit a somewhat restricted passage of fluid from the pipe 4 suplying hot water. In Fig. 11 a continued rotation of the plug within the valve body will swing inlet port 2. into registration, in maximum relation with the left hand end of the plug opening 12, and consequently an unrestricted flow of liquid will take place through the entire area of the inlet port 2. It is apparent that up tothis point of rotation the inlet port 3 andthe plug opening 13 will have not yet come in registration and consequently that no flow of fluid through the pipe 5 supplying coldwater will take place. Upon still further rotation of the plug into the position shown in Fig. 12, it will be seen that port 3 and opening 13 will have arrived into partial registration. It will further be observed that by reason of the circumferential elongation of the opening 12, port-2 "is still in maximum registration with said opening 12, near the central part of its length. In consequence fluid .will flow simultaneously through both supply ipes'; flowingin full "volume, through the 0t supply ;inlet, an d in partial volume through the cold su ply inlet. In Fig. 13 the position of the sur aces p and b are. such that the left ha'nd'end'ofopening 13 will have arrived in registration in maximum relation: with the inlet port 3;

port 2 at the. same time, by reason of theelongated form-of opening 12, beingin registration in maximum relation withi-the right hand end of saidopeningxli In consequence of the simultaneous-i registration in maximum relation of inlet; ports; and 3 ,respectively with plug openings, I 12 and. .13, ,.'lthe fluid from both sourcesof suppl' will flow in equal volume through" h'said plug openings, and the, flow" throng sthef valve will beat a.imaximum rate,-.as -determined by the aggregate areas" ofithe two inlet por'ts.-- In Fig 14 the further rotation 0f both sai inlet-port's and throu the plug will-operate to partly close the inletport 2,;inlet :port 3', however, by reason ofthe circumferential elongation of opening .13 beiiigjdimini'shed as toits opening. In Fig. 15 i-port 2 isentirely closed, port 3 beingstill complete registration, with the right hand iendfiof openmg 13. In oonse-' quence cold fiuid alone will flow in full supply through" the 'valve'. On further rotation to the-polnt' indicatedin Fi 16 the port '13 is only open to a part 0 its area, and

the flow of cold supply will be correspondingly checked. In Fig. 17; both ports are completclyclosed and flow of fluid through the valve is entirely cut off.

From the above it is apparent thatby the rotation of the plug 8 by means of the handle such an adjustment of the valve may be effected as will control the amount of flow of fluid either from the hot supply or of the cold supply separately or will permit such an intermingling of the two supplies as will bring about a discharge of the desired temperature. A still further control of the passage of fluid through the valve, by which more especially the rate of such flow may be regulated without affecting the proportions in which the supply is intermingled maybe effected by longitudinally shifting the position of the plug in the valve body so as to change the position of the plug openings with reference to the inlet ports. Such longitudinal movement is preferably effected in the following manner. The controlling handle as more clearly shown in Figs. 2 and T, is formed with forked portions 11 preferably curved substantially as shown in the drawings, and arranged to straddle the tongue 9. Said forked portions 11 are provided with external marginal rims 11 which are adapted to slidingly engage within lateral grooves 10 cut on the internal faces of a forked extension 10 forming a part of the bushing 10. The tongue 9 is pivotally secured to said forked portions 11- by a pin 17. Said pin 17is located eccentrically with respect to the center of an arc to which the curvature of the ribs 1'1 preferably conforms. Henceit is apparent that upon the rotation of the lever 11 in a vertical plane, an up and down displacement of pin 17 will take place, which, starting from thelowest position of the pin 17 as shown in F ig. 3, and corresponding to the normal position of lever 11, will reach its maximum upward displacementwhen the lever 11 is thrown over into itsv extreme limiting position as shown in Fig. 1. The plug 8, engaging said pin 17 through the tongue 9 will share in such longitudinal movement. The height of the inlet ports 2 and 3, and the width of the plug openings 12 and 13 and the longitudinal location of said openings upon .the plug, are so related to the amount of the longitu- (linal travel of said plug, that such plug openings, although exactly registering as to their width with the height of the inlet openings, in the normal or lowest position of the plug, as shown in Fig. 3, will be dis placed by the longitudinal movement of the plug until in. the position of the plug corre: sponding tothe maximum displacement of the same, said plug openings and said inlet ports are no longer in registration. Hence by swinging the control lever 11 in the vertical plane, the amount of the openings fluid therethrough may be varied, irrespective of the position of the angular position of said handle 11".

The manner in which the rate of flow through the valve is controlled by the manipulation of the control lever 11 is more clearly understood by reference to the developed views shown in Figs. 18, 19 and 20. In such figures, as before 7) represents the surface of the valve body having the inlet ports 2 and 3 located therein and p repre sents the surface of the plug having the plug openings 12 and 13 formed therein. In Fig. 18 the plug, in the position of rotation assumed in Fig. 11 is represented as shifted, upwardly with respect to the valve surface 6 for substantially one half the width of the valve'opening. As in Fig. 11, only fluids supplied through the inlet port 2 will flow throughthe valve, but the rate of ow of such fluid will be substantially only half as great in Fig. 18 as in Fig. 11.

' In Fig. 19 the angular position of the plug in the valve is supposed to be identical with that represented in Fig. 13 but the plug is assumed to have been so shifted longitudinally in the valve body as to nearly close the inlet ports. As in Fig. 13 fluid will flow in equal volume through both supply pipes through the valve. However, although the relative portions of fluid supplied from each pipe is the same, the rate of flow through the valve will be greatly diminished in comparison with that of Fig. 13. In Fig. 20 the plug, which is assumed to bein the angular position represented by Fig. 14 is assumed to have been shifted for about one third of the Width of the inlet ports. The relative proportion of fluid flowing through each supply pipe will remain unaltered but the rate of such flow will be less in Fig. 20 than that shown in Fig.14.

i It is therefore apparent that my invention affords a means not only for adjusting the proportions in which supply fluids are intermin led, but also a means by which the rate of t 1e intermingled fluids may be controlled Without disturbance to proportions to the intermingled fluid.

While I have hereinabove described my. invention as applied in its preferred form to a faucet controlling the flow of hot andcold water, it will be obvious that my invention may be applied .in many modified forms without departure from the principles and the spirit of the invention, and for this reason I do not Wish to be understood as limiting myself to the precise form and arrangement of the several parts exactly as hereinbefore set forth; nor do I wish to be understood as limiting myself to the employment of my inventionin connection with a valve of any particular type nor for any special use, since it is evident that the invention iscapable oi adaptation to valves ent is,+
